Oscillators Procurement Notes

Verify the specific suffix 'A2T' against official manufacturer documentation to confirm the exact voltage and temperature specifications, as series variants may differ. Confirm that the 2.5V supply requirement aligns with your system design, as other models in the 637L series may utilize 3.3V. Ensure the -10°C to 60°C industrial temperature range meets your environmental requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when a 122.88 MHz clock signal with LVDS outputs is required. The ±20ppm stability offers precision for synchronous data links. Consider the 2.5V supply constraint compared to standard 3.3V logic levels. The 6-SMD footprint allows for automated assembly. Verify compatibility with target receiver inputs for LVDS signal integrity.
